On Pentecost, the Spirit did His work of making the apostles bold to speak the Gospel of Christ. He did His work of making the people understand and take to heart the sermon Peter preached. He granted repentance of sin and faith in Christ, He gave joyful fellowship and communion together with His saints, a devotion to the apostles’ teaching in the word. This is what true repentance looks like, not just in the emotional moment, but down the road.
The question is the same for us. Are our lives characterized by repentance, or self-justification? Faith in God or self-reliant pride? Joyful fellowship, or at-a-distance criticism and judgment? Devotion to the Spirit’s teaching in the Word, or assuming we know what it says and going with our gut?
The Spirit cuts hearts to the quick. Let Him cut into yours now. This Jesus, whom you crucified by your sins, God has made Lord and Christ. This reminds us of our need to confess our sins.
